TRACK-BRAKE.

SPECIFICATION forming part of Letters Patent No. 716,616, dated December23, 1902.

Application tiled June 30, 1902. Serial No'. 113,804. (No model.)

To cir/ZZ whom, 25 may cm2/cern: l

Be it known that we, HERBERT L. BAINES, residing at Manch Chunk, andJOHN EDWARD VAASER, residing at East Manch Chunk, in

the county of Carbon and State of Pennsylvania, citizens of the UnitedStates, have invented a new and useful Track- Brake, of which thefollowing is a specification.

The invention relates to improvements in 1o track-brakes.

The object of the present invention is to improve the construction oftrack-brakes and to provide au exceedingly simple and inexpensive oue ofgreat strength and durability I5 which will be positive and reliable inoperation in all weather conditions and which Will be adapted to beoperated from either end of a car.

A further object of the invention is to prozo vide a brake of thischaracter Which will be capable of instantaneous application and whichwill be equally effective with light and heavy loads.

The invention consists in the construction z5 and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side eleva# 3o tion of a track-brakeconstructed in accordance with this invention. Fig. 2 is a plan View.Fig. 3 is an end elevation of the shoe.

Like numerals of reference designate corresponding parts in all thefigures ofthe drawings.

1 designates a brake-shoe having a tapering inner portion presenting acurved upper edge 2 to conform to the configuration of a car-Wheel andprovided adjacent to the inner to face of the shoe with a groove 3 toreceive the flange of the carwheel when the brake is applied, asillustrated in dotted lines in Fig. 1 of the drawings. The brake-shoe isprovided at its inner face with a depending bottom flange 4, arranged toengage the inner face of a rail. By this construction the brake-shoewhen applied is firmly interlocked with the Wheel and with the rail andis securely held against lateral displacement. The brake-shoe is alsoprovided at its bottom with a recess in 5o which is secured a steelfriction-block 5,Which is adapted to receive the greater portion of thewear and which may be readily replaced when worn. The block 5 isdetachablysecured `within the recess by bolts 6, having countersunkheads at the outer face ot' the block and provided at the inner face ofthe brakeshoe with nuts, as clearly shown in Fig. 3.

The brake-shoes at the opposite sides of a car are connected by a pairof transverse rods 6o 7 and 8 and are supported by links 9 and 10,arranged in pairs adjacent to each brake-shoe and pivoted at their upperends to brackets ll. Each bracket 1l is provided with an. inclined arm12 and an upright arm 13, which 65 is secured to the upright portion ofan anglebeam 14, and the latter is designed to be con nected with thetruck-frame or other portion of the car by any suitable means. Theinclined arm 12 is provided with inner and outer 7o portions arranged atan angle to each other, the upper end ot the links being connected Withthe terminals of the outer portion of the inclined arm.

The downward movementof the brake-shoe is limited by a bar 15, pivotedat its lower or inner end by a suitable fastening device 16 to thebrake-shoe and terminating at its upper or outer endin a hook 17, whichis adapted to engage the horizontal flange or portion of 8o the beam 14,as illustrated in Fig. 1 of the drawings. The bar 15 is arranged ataslight inclination and is supported by a guide 18, having an opening toreceive the bar 15 and composed of a horizontal upper portion and aninclined depending portion. The hook prevents the car-Wheel from ridingover the brake-shoe. The upper horizontal portion of the guide 1S isperforated for the reception of bolts 19 for securi-ng the guide to theangle- 9o iron beam, and onebf the transverse rods is connected with achain 20, which may extend to any suitable operating mechanism forcontrolling the brake. When the chain is slackened, the brake-shoe willdrop by gravity, and an instantaneous application of the brake isthereby obtained, and the greater the load the greater will be theett'ect of the brake.

The brake is not affected by the weather, and the brake-shoes of a carwill lock the same against movement in either direction.

l. In a device of the class described, the

-combination of a brake-shoe, means for suspending the brake-shoe andfor permitting the same to swingl upward and downward, a fixed guide anda bar connected with the shoe and slidable in the guide and terminatingin a hook arranged to engage the guide to limit the downward movement ofthe shoe, substantially as described.

2. In a device of the class described, the combination with a support,of a brake-shoe suspended from the support, a guide secured to thesupport, and a bar connected with the brake-sh0e and arranged in theguide for limiting the movement of the brakeshoe, substantially asdescribed.

3. In a device of the class described, the combination with a support,of a brake-shoe suspended from the support, a guide depending from thesupport, and a bar pivotaily connected with the brake-shoe and arrangedin the guide and terminating in a hook for limiting the movement of thebrake-shoe, substantially as described.

4. In a device of the class described, the

combination with a support, of a bracket secured to the support andhaving a projecting arm, a brake shoe, links suspending the brake-shoefrom the arm of the bracket, a guide secured to the support, and a barconnectedwith the brake-shoe and arranged in the guide and provided withmeans for limiting the movement of the brake-shoe, substantially asdescribed.

5. In a device of the class described, the combination with anangie-iron beam, of a bracket composed of an upright arm secured to oneof the flanges of the beam, and an inclined arm extending from the beam,a brakeshoe, links connected with the inclined arm and with thebrake-shoe, a guide secured to the angle-iron beam and dependingtherefrom and having an opening, and a bar pivoted to the brake-shoe andarranged in the opening of the guide and terminating in a hook forengaging the beam,substantia11y as described. In testimony that we claimthe foregoing as our own we have hereto affixed our signatures in thepresence of two witnesses.
